HYDROCARBON BLOW-TORCH.

Specification of Letters Patent.

Patented Apr. *7, 191st.

To all whom it may concern Be it known that we, Josnrn L. SHEARD and EDGAR E. DUTTON, citizens of the United States, residing at Fallsdale, in the county of Wayne and State of Pennsylvania, have invented a new and useful Hydrocarbon Blow-Torch, of which the following is a specification.

The present invention appertains to blow torches, and aims 'to provide a novel and improved device of that character.

It is the object of the present invention to provide a hydrocarbon blow torch embodying a fuel tank for font carrying a burner, and a supporting base for the tank, for permitting the tank to be adjusted at various angular positions with respect to the base, whereby the device may be employed upon inclined or sloping surfaces, as well as level ones, and whereby the burner may be tilted for purpose of brazing, or the like.

Another object of the present invention is to provide a blow torch of the nature indicated, the burner and tank of which embody means for supporting a plumbers solder tool or iron, in order that the bit may be readily heated.

A further object of the present invention is the provision of a unique burner, embody ing novel means for controlling the discharge of vapors.

The present invention also comprehends the provision of a hydrocarbon blow torch embodying a novel assemblage of parts, to best adapt the device for the purposes intended, and whereby the structure will be comparatively simple, compact and inexpensive, as well as convenient, practical and eflicient in its use.

l/Vith the foregoing and other objectsin view, which will be apparent as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a side elevation of the blow torch. Fig. 2 is a rear or back view thereof.

Fig. 3 is a horizontal section taken on the line 33 of Fig. 1. Fig. 4 is an enlarged sectional detail of the burner. Fig. 5 is plan view in detail of the vapor controlling means.

In carrying out the present invention, the tank or font 1, for the kerosene or other hydrocarbonous fuel, is carried by a base 2, which is preferably in the form of a ring or annulus, and which has a pair of upstanding resilient standards or arms 3, the upper terminal portions of which receive the trunnions 4 attached to diametrically opposite sides of the tank 1. The trunnions 1 are journaled through the standards 3 and permit the tank or can 1 to be tilted at various angles with respect to the base, a clamping nut or hand wheel 5 being preferably threaded upon one of the trunnions 4, to clamp the fuel tank or can at any position to which it is swung.

The fuel tank 1 is provided with a handle 6 upon its upper end or top, which is preferably disposed at right angles to the common axis of the trunnions 4L, and a pump 7 is carried bythe back side of the tank 1, for injecting air into the tank to bring the fuel under pressure so as to feed the fuel to the burner designated generally at 8.

The burner 8, which is disposed at the front side of the tank 1, comprises an upright spiral generating or retort coil 9, the upper terminal of which is connected to the lower portion of the tank 1, by means of a supply pipe 10. The coil 9 is surrounded ,by a casing or flue 11, having the pivoted damper 12 at its lower end, and having a collar 13 slipped over its upper end and provided with brackets 14- supporting a ring or annulus 15. solder iron, or any other object to be heated,

may be placed upon the ring or annulus 15 over the coil 9, the flames passing upwardly through the coil 9, as will hereinafter appear.

Upon that end of the handle 6 remote from the burner is secured a cross rod 16, preferably having its ends upturned, whereby the said rod provides a seat for the shank of a plumbers solder iron, or the like, which is of advantage in connection with the ring or annular seat 15.

To the lower end or extremity of the coil 9, is attached one arm or branch of an elbow The bit of a plumbers- 9 17, having a strainer 17, the other or free 5 of the coil 9, or being co-axial with the coil.

From the retort or generating coil 9, the vapor is adapted to be discharged through the aperture 18 axially through the coil, to heat the coil for the generation of the fuel, and to heat an object placed upon the annular seat 15.

The discharge of vapor through the aperture 18 is controlled as follows: The free arm of the elbow 17 is provided with a radial horizontally projecting arm 19 havmg a longitudinal slot or opening, and a bracket 20 comprising a doubled bar, or the a base, a fuel tank plvotally carried thereby, an upright burner disposed at one side of like, has one end clamped upon the arm 19 by means of a clamping screw or the like, 21, engaged through the slotted arm 19 and taking into the respective extremity of the bracket 20. The upper free portion or leaf 22 of the bracket 20 is slightly raised, and has pivoted thereto, a controlling lever 28, the inner end of which projects over the aperture 18, and carries a depending needle valve 24 projecting toward and cooperating with the aperture 18. An adjusting screw 25 is threaded through the outer end of the lever 23, to seat upon the free end of the bracket 20. A brace 26 is preferably engaged at one end to the screw 21, and at the other end to the tank or can 1, to assist in supporting the burner.

When the burner is in operation, the flames will impinge against the coil 9 to generate the fuel, and will pass upwardly to heat an article placed upon the burner, it being observed that the needle valve 24 in standing over the aperture 18, will some- 7 What serve to spread the flames against the convolutions of the retort coil, the casing or flue 11 confining the flames, and the damper 12 controlling the current of air passing upwardly through the flue 11 to assist in combustion. By adjusting the screw 25, the lever 23, may be adjusted to regulate the position of the needle valve 24:, whereby the flow of vapor may be regulated to a nicety, it being observed that the outer ends of the bracket 20 and lever 23 pass through an opening provided in the casing or flue 11. By properly manipulating the lever 23, any matter accumulating within the aperture 18, may be dislodged, to prevent the aperture from becoming clogged up.

Attention is directed to the fact that the base 2 may be set upon an inclined surface, such as a roof of any pitch, it being possible to adjust the tank or font 1 to vertical position, in order that the object to be heated may be properly supported upon the burner and. tank.

As illustrated in Fig. 1, a plumbers soldering tool or iron T may be conveniently placed upon the seats 15 16, the annular seat 15 accommodating the bit, while the seat 16 is adapted to receive the shank or handle.

It is also possible to tilt the tank 1, or to swing it to horizontal'position, in order that the burner may be employed for brazing,

and kindred purposes.
